^ Geeez Ghost, at least have the common courtesy to put that in a spoiler alert click option. Some people just have no class these days.

@all the mad S400s moddsters

Man I am with ghost and hersey, etc on this one. I really feel no need or have the need to modd these S400s beyond the point of that taped bass port/ pad changes. But I'll try that ULTRA TAPE mod of merci's since i promised i'll do it. Happy modding you'll and continue to enjoy them S400s. cuz lord knows i haven't. LoL My damn ULTIMATE Modded S500s got all the love for now.

I think I should change the title of this thread to "The slimming thread" ....one look at the pictures and you'll lose your appetite !

"tried hd25 velours. still piercing. there is nother problem for me: these nicely build but crapy sounding headphones have zero soundstage, layering and imaging. even the already congested sounding k518 has better depth and layering. maybe it is just me, but i think i stumbled in the overhype trap again."

I don't have the s500's but people have said that those are much better than the s400's. If you're not going to mod (damp the resonance on the plastic) the 400's, I'd save your money for something else.

i can agree with the soundstage if your comming open back headphones, but thats something you should expect if you are buying closed portable phones, if people stumble on the hype train its cause they are not reading the thread, it has being said many times that the soundstage is no huge/big, its like any ohter portable closed HP.

its like expecting 500 horse power from a Honda Accord, people should read the spec sheets.

I too was a little disappointed with the soundstage at first. But coming from open phones I knew it wouldn't be fair to compare. The clarity and detail however help to make up for shortfalls in soundstage.

those who have bought the dt250 velour pads for their htf600 will have all they need.

they come with plastic plates for the pads (on the left), and these we will be installing on the s400.

problem is that when you open the s400 you have to go through the wire, so snap it (start with a cut and bend it back and forth just enough)

(im actually a very skinny guy... picture makes my hand look fat) now we ready, pull th wire out to give yourself space to put it through, should end up like this

now the hard part were the screws, i was not sure if they would reach with the extra layer of plastic and i was having trouble. i founf a screw that was just a bit longer that worked great but 1 was not going to cut it.

somehow on the second pad the screws found their mark and just reached and were secure. the fist one took some marksmanship to get right, but within a few minutes they were all screwed in with the original screws. now they came with filter/padding as well that fit snugly in the pads (i like it without the padding).

the highs are now much better, and since the drivers are farther bass is not as strong which is a minus for me, but im thinking this would be perfect for the s500. comfort is waay better now, and will see how it goes.

When i originally thought about this mod i didnt think it was going to work and threw out those plastic plates, luckily risenfallen answered the call and sent me his spares.

Woah, epic mod!!!! I can't try it out since I sold my s400's, but it looks awesome.

Just this quick I'm sold. I've been lurking around this thread but I haven't pulled the trigger because I held to find on ear types uncomfortable. When I saw dt250 pads show up I remembered something I saw years ago about Sony mdr-v6 taking the same pads. I have a set of mdr-v7 that are the most comfortable_ thing in the world. And my v7 need new pads, so I have an excuse to try a couple. Thanks, I'll be buying soon!

....SFW Alert....Sorry SF and Ghost, today there is one less ha-s400 purist in the world...yeah I know I promised not to stray...but today I had some time on my hands and modded the darn things (tape, driver insulation/padding)...sorry no pictures unfortunately as I was deep in thought and security said no flash photography...I used some spaceage white cloth tape on entire project behind the driver and on the plastic surfaces (wifees in the medical research industry) don't know what kind but it looked/sounded and felt the best out of duct, electrical and masking...insulated around the driver with adhesive insulation and used two layers of cloth (from minipad, yes that's right) she won't miss it for a little while...and used double sided aircraft carpet tape over the white cloth tape (very thin) to hold the minipad layers(2) in place....did not cover any sinks or ports (the ones covered with the original white porous tape...tried to make each side as identical as possible...those driver connections look a little frighteningly fragile...thought I might snap one just opening and closing...but A-O.K.

...O/K enough of how I did it and on to the sound...well all I can say is great job to you guys out there...it really does bring these guys to a whole different level...it is not subtle as others I have tried have been..again it is "not" subtle...greater focus, clarity, cohesiveness, great bass and micro detailed layers I have never heard pop right out!!...still has everything I have always loved about these cans but really brings a tear to your eye for $25...crazy good...I guess everybody is going to get different results depending on materials and procedure but I waited too long for this...I guess the fear of destroying these and having to break in another pair took hold of me... but that thought of elevating these jewels just overcame me...Great job to Char and the gang for these illustrated processes...never thought they were unlistenable like Char but they sure sound fantastic now...like I just got a new pair of cans today!!!...very intoxicating sound now...must be the white ones!!!
